SCEA 1.5/1.6

Rumors that SUN is coming out with a new SCEA 1.5 in march. is there any specific recommended reading for this certification as well. Maybe it's better to wait for the new one if you recently took the SCJD certification.

For pretty much every other question you have, the answers are one of the following:

No

We don't know

We don't know when

We won't know until Sun officially releases the exam

Not yet

There aren't any yet

SCEA 5 Multiple Choice Testing Objectives "DRAFT"

Section 1: Application Design Concepts and Principles

1.1Explain the main advantages of an object oriented approach to system design including the effect of encapsulation, inheritance, delegation, and the use of interfaces, on architectural characteristics. 1.2Describe how the principle of �separation of concerns� has been applied to the main system tiers of a Java EE application. Tiers include client (both GUI and web), web (web container), business (EJB container), integration, and resource tiers. 1.3Describe how the principle of �separation of concerns� has been applied to the layers of a Java EE application. Layers include application, virtual platform (component APIs), application infrastructure (containers), enterprise services (operating system and virtualization), compute and storage, and the networking infrastructure layers.

Section 3:Integration and Messaging

3.1Explain possible approaches for communicating with an external system from a Java EE-based system given an outline description of those systems and outline the benefits and drawbacks of each approach. 3.2Explain typical uses of Web Services and XML over HTTP as mechanisms to integrate distinct software components. 3.3Explain how Java Connector Architecture and JMS are used to integrate distinct software components as part of an overall Java EE application.

Section 4: Business Tier Technologies

4.1Explain and contrast uses for Entity Beans, Entity Classes, Stateful and Stateless Session Beans, and Message Driven Beans and understand the advantages and disadvantages of each type. 4.2Explain and contrast the following persistence strategies: Container Managed Persistence (CMP) BMP, JDO, JPA, ORM and using DAOs (Data Access Objects) and direct JDBC-based persistence under the following headings: ease of development, performance, scalability, extensibility and security. 4.3Explain how Java EE supports the deployment of server-side components implemented as Web Services and the advantages and disadvantages of adopting such an approach. 4.4Explain the benefits of the EJB3 development model over previous EJB generations for ease of development including how the EJB container simplifies EJB development.

Section 5: Web Tier Technologies

5.1State the benefits and drawbacks of adopting a web framework in designing a Java EE application 5.2Explain standard uses for JSP and Servlet technologies in a typical Java EE application. 5.3Explain standard uses for JSF technology in a typical Java EE application. 5.4Given a system requirements definition, explain and justify your rationale for choosing a web-centric or EJB-centric implementation to solve the requirements. Web-centric means that you are providing a solution that does not use EJBs. EJB-centric solution will require an application server that supports EJBs.

Section 6: Applicability of Java EE Technology

6.1Given a specified business problem, design a modular solution implemented using Java EE which solves that business problem. 6.2Explain how the Java EE platform enables service oriented architecture (SOA) -based applications. 6.3Explain how you would design a Java EE application to repeatedly measure critical non-functional requirements and outline a standard process with specific strategies to refactor that application to improve on the results of the measurements.

Section 7: Patterns

7.1From a list, select the most appropriate pattern for a given scenario. Patterns are limited to those documented in the book - Alur, Crupi and Malks (2003). Core J2EE Patterns: Best Practices and Design Strategies 2nd Edition and named using the names given in that book. 7.2From a list, select the most appropriate pattern for a given scenario. Patterns are limited to those documented in the book - Gamma, Erich; Richard Helm, Ralph Johnson, and John Vlissides (1995). Design Patterns: Elements of Reusable Object-Oriented Software and are named using the names given in that book. 7.3Select from a list the benefits and drawbacks of a pattern drawn from the book - Gamma, Erich; Richard Helm, Ralph Johnson, and John Vlissides (1995). Design Patterns: Elements of Reusable Object-Oriented Software. 7.4Select from a list the benefits and drawbacks of a specified Core J2EE pattern drawn from the book � Alur, Crupi and Malks (2003). Core J2EE Patterns: Best Practices and Design Strategies 2nd Edition.

Section 8: Security

8.1Explain the client-side security model for the Java SE environment, including the Web Start and applet deployment modes. 8.2Given an architectural system specification, select appropriate locations for implementation of specified security features, and select suitable technologies for implementation of those features 8.3Identify and classify potential threats to a system and describe how a given architecture will address the threats. 8.4Describe the commonly used declarative and programmatic methods used to secure applications built on the Java EE platform, for example use of deployment descriptors and JAAS.
